SPRING-SEAT FOR VEHICLES.

SPECIFICATION formingpart of Letters Patent No. 290,487, dated December 18, 1883. Application filed September 24., 1883. (No model.)

fo all whom, it may concern.'

Be it known that I, CHARLES F. LnNoAsrnR,

Traverse and State of Michigan, have invented certain new and useful Improvements in Spring-Seats for Vehicles 5 andIdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this speciiication.

This invention relates to certain new and useful improvements in spring-seats for vehicles, its object being to provide a spring which will prevent a side and back motion; also, to provide a seat which will have an easy vertical movement, which spring will not project in front of the seat; and it consists in providing a seat with a straight supporting-bar with downwardly-projecting lugs, which will rest upon the side-boards of a wagon, said seat having attached to the under side of the same front springs,which proj ect laterally, and rearwardly-projecting springs, which are attached to the front portion of the under side of the seat, said springs being clipped, respectively, to the side and rear ends of the supportingbar, the construction and arrangement of the parts being illustrated in the accompanying drawings, in which- Figure l is a perspective view; Fig. 2, a side view, and Fig. 3 a detailed perspective view of one of the side springs detached.

In the accompanying drawings, which illustrate my invention, A represents a seat of ordinary construction, to the front portion of which are attached springs B B, theupper ends of which are attached to the under side of the seat near its front edge and ata slight distance from the side edges. This spring is curved downwardly, as shown at b, and its lower end is provided with an eyeb, which is formed by bending the metal upon itself. The straight upper portion of this spring is provided with two or more perforations, by means of which it is secured to the under side of the seat by bolts or other attaching means. C represents a double curved spring, which is attached to the under side of the seat A adjacent to its edges, said spring having astraight front portion, c, and a double central a, the end opposite the straight end c being bent over upon itself, so as to form the spiral, as shown at a', the extreme end of the spring within the spiral being bent upon itself, so as to form an eye. These springs B and C are attached to astraight bar of malleable iron, (indicated by the letter D.) This bar is provided with downwardly-projecting lugs d d, and at its front end with a downwardly-projecting portion, d. Opposite this front lug, d@ arebent at right angles therewith two horizontal wings, d" d, which are perforated for the reception of the bolt e, which passes through the eye b', formed on the end of the spring B.

curved portion,

' At the rear end of the bar are provided two upwardly-projecting wings, f, through which passes a bolt for the purpose of attaching thereto the end of thespring C. The downwardly# projecting lugs formed on the under side of this bar and the downwardly-projecting portion d embrace the upper edge of the sideboards of a wagon and hold the seat from lateral displacement. It will be noticed that by the constructionl hereinbefore described this bar vD is made of a single piece of metal,

the lugs and wings or clips being formed therefrom.

In a seat provided with springs and a supporting-bar, or constructed as hereinbefore described, all side and backward and forward movement of the seat is prevented, and the seat will have an easy vertical movement. A seat thus constructed is very light and durable, and the springs will brace the seat in both directions, and said springs will not form an obstruction in getting in andout of the wagon, as they do not extend in front of the seat. The same is ornamental, and will add considerably to the appearance of the vehicle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a springseat for. vehicles, the springs B B, attached to the front edge of a seat, and the rearwardly-projecting springs C C, placed at right angles with the front springs, said IOG springs being connected to each other by a I rigid scat-supporting bar, substantially as described.

2. In combination with a vehicle-seat, the springs B B, having their outer ends curved downwardly and inwardly, and the spring C, attached to theseat at right angleswith the front spring and secured to cach other by a rigid connecting-bar having downwardlyproiecting lugs formed upon the same, substantially as described.

3. The connecting and supporting bar D, having a flat under surface, and provided at its ends with downwardly-projccting lugs formed i ntegral therewith, and having attached to said bar upwardlyprojecting springs, substantially as shown.

4. The supporting-bar I), having downwardly-projecting lugs and provided with outwardly-projecting side pieces or wings d at its front end, and upwardly-projecting side pieces or wingsj at its rear end, in combination with the springs B and C, having eyes formed at their lower ends, the same being attached to a seat, substantially as shown.

5. In a spring wagon-scat, the springs C C, attached near the front portion of the seat parallel with its sides, said springs projecting downwardly under the seat, and provided with coiled ends a a', and springs B B, attached under the front edge of the scat and parallel to said edge,with downwardly-curvedportions, in combination with the bars D D, having downwardly-proj ecting lugs d, and upwardlyprojecting side pieces f at its rear end and outwardly-projecting pieces d d at its front end, forming a ineans for attaching the springs thereto, the parts being organized and coinbincd substantially as shown.

In testimony whereof I aiix my signature in presence of two witnesses.

CHARLES F. LANCASTER.
